POWER-WINCH.

SPECIFICATION forming part of Letters Patent No. 614,309, dated November 15, 1898.

Application filed April 25, 1898. Serial No. 678,758. (No model.)

To ctZZ whom it may concern.-

Be it known that we, JOHN W. POPE, a resident of Decorah, county of W'inneshiek, and WVILLIAM O. MEYRICK, a resident of Des Moines, county of Polk, State of Iowa, citizens of the United States of America, have invented certain new and useful Improvements in Power-'Winches, of which the following is a description.

Referring to the accompanying drawings, wherein like reference-letters indicate like or corresponding part-s, Figure l is a perspective view of our improved device. Fig. 2 is a similar view with the lever and cap removed. Fig. 3 is a central vertical section of our device. Fig. 4 is a horizontal section on line 4 4: of Fig. 3. Fig. 5 is a bottom plan of the top O,showin g the ratchet connection with the drum B. Fig. 6 is a bottom plan of the cap and lever seat. Fig. 7 is a perspective view of the bottom of the block.

The object of our invention is to provide a simple,efficient, and economical winch which may be utilized for trying and difficult work' such, for example, as stump-pulling.

To this end it is embodied in a novel con struction and combination of elements shown and described, and particularly pointed out in the claims.

In the drawings, A represents a suitable base, 13 the winding-drum, and O the top of the winch or capstan. The top of the drum, extending through the top of the winch, terminates in the cam-face 19, provided with shoulders 19, adapted to interlock with the similar shoulders 61 in the cam-face d of the locking-block D.

E is the cap and lever seat, adapted to.v be placed over and inclose the locking-block D. The lugs e are designed to register with the groove or depression 01 in the block D, Fig. 4, thus allowing the block a vertical movement within the cap without disconnecting it therefrom. The cap has at its base a projecting flange 6, over which an arm or arms F, firmly secured to the top O, extends, firmly binding the cap to the top C, but permitting rotation thereon.

G is the lever or sweep, to which power may be applied to operate the machine.

H is a bar or rod extending from the lever to the block I), to which it is suitably connected, and I is a cam-lever connected to the bar or rod H, by means of which the block D may be raised to clear the cam b and release the lever G from connection with the drum.

K is a ratchet-lever preferably secured to the bottom of the top 0 and engaging with the ratchet B of the drum to take up and retain all the advantage gained by the opera tion of the device.

The mode of operation is as follows: The winch being suitably secured by the anchor rope L, secured on the standard M, or in any other preferred manner, the cam-lever I is operated to bring the locking-block D into engagement with the cam top I) of the drum B. The rotation of the sweep or lever G will then operate the drum B and draw on the cable wound thereon. The ratchet K takes up and retains the drum in the position gained. If for any reason the sweep or lever G cannot be given a full rotation or more advantage can be gained by giving a partial revolution only, it may be reversed, when the block D, being vertically movable in its cap E, as described, will ride over the cam-face Z7, when it will again drop into position and the lever again be rotated to operate the drum,

as before.

When it becomes necessary or desirable to reverse the drum B, the cam-lever I is operated to lift the block D out of engagement with the drum. The ratchet K may then be released, and the drum will then be free to reverse without afiecting the lever G, which is then disengaged from the drum.

It is obvious, after pointing out our improvements, that minor modifications may be made without departing from the spirit of our invention. Hence we do not Wish to be limited to the exact construction shown, the broad idea of our invention consisting in the construction of a device of the kind described provided with a movable locking-block disconnected from the other parts of the machine and serving as an intermediate connection between the operating means within which it is inclosed and the drum, thus controlling the operation of the latter.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a winch, the combination of a base, a winding-drum provided with a clutch 1nemher, an operating means for the drum and disconnected therefrom, and a movable clutch member inclosed within said operating means and serving as an intermediate connection between the operating means and the drum, substantially as described.

2. In a winch, the base, the top, a windingdrum provided with a clutch top, a rotatable cap for the end of the drum, and means for rotating the cap, in combination with a clutchblock adapted to engage the drum, located within the cap and movable therein to engage or disengage the drum, and means for causing the block to rotate with the cap, whereby the clutch-block forms an intermediate conneetion between the power and the drum, substantially as described.

3. In a winch, the base, the top, a windingdrum provided with a clutch top, a rotatable cap for the end of the drum and means for rotating the cap in combination withaclutchblock adapted to engage the drum, located within the cap and movable therein to engage or disengage the drum, means for causing the block to rotate with the cap and means for disengaging the clutch-block from the drum whereby the block forms an intermediate connection between the power and the drum and may be engaged or disengaged from the drum at will, substantiallyas described.

4:. In a device of the kind described, the base, the top,the winding-drum provided with the clutch top and means to hold the drum against reversal, the rotatable cap and means for rotating the same, in combination with the clutch-block adapted to engage the drum, located within the cap and movable therein to engage or disengage the drum, means to disengage the clutch-block at will and means for causing the block to rotate with the cap, substantially as described.

5. In a device of the kind described, the base, the top, a vertical winding-drum provided with a clutch top, a rotatable cap for the end of the drum and means for rotating the cap, in combination with a clutch-block adapted to engage the drum, said clutchblock being located within the cap and Vertically movable therein, means to disengage the clutch-block from the drum at will and means for causing the block to rotate with the cap, substantially as described.

6. In a device of the kind described, the base, the top, a vertical winding-drum provid ed with a clutch top, a rotatable cap for the end of the drum, and means for rotating the cap, in combination with a clutch block adapted to engage the drum, said clutchblock being located within the cap and vertically movable therein, means for causing the block to rotate with the cap, a rod or bar extending through the cap and attached to the block, and means for lifting the rod or bar and block at will, substantially as described and for the purpose set forth.
